244 CAUSES or glandkus. 



the nose or lungs of a glandered horse, or from the open buds of a 

 farcied one ] Surely, that which can conduct poison from the 

 dung or urine upon the floor of the stable, can transport virus 

 from one horse's nostrils into those of another; — and, surely, the 

 virus emanating from a chancrous surface must be as virulent and 

 efficacious as any generated in the dung, the urine, or the breath 

 of horses in health *. 



Thirdly : no doubt has ever been entertained by me of the 

 spontaneous origin of glanders and farcy — of their origin apart 

 from the influence of contagion. Coleman, whose field for ob- 

 servation was greater than almost any man has enjoyed either 

 before or since — he having had the Army, the Ordnance, the Vete- 

 rinary College, and some private practice besides, to range over 

 — adduced much satisfactory evidence in proof of this fact. He 

 shewed that these diseases, on several occasions, had made their 

 appearance in situations never inhabited by horses before, and 

 then, for the first time, by horses at the time of their entry in 

 apparently perfect health ; in new, public, and private stables, and 

 on board of new ships t. And he said that the morbific agent was 

 the poison the healthy inhabitants of such uncontaminated abodes 

 themselves generated, by being shut up without due or proper 

 ventilation. 



Smith contended as strongly as Coleman for the origin of 

 glanders independent of contagion, and admitted how frequently and 

 commonly the disease broke out in foul and unventilated stables; 



* " A glandered horse may contaminate the air of a stable to such a degree 

 that horses breathing the same air may become infected with the disease, al- 

 though the infected may never come in contact with the infecting horse. 

 Fortunately, glanders is not so infectious as some other diseases to which 

 horses are liable, otherwise the breed would soon become extinct." — Vide cm 

 admirable article " On the External Causes of Disease^''' by W. F. Karkeek, 

 V.S., Truro, in The Veterinakian /or 1833. 



f Although some doubt has been cast by " an old artillery officer" on 

 Coleman's account of the Quiberon expedition (see Veterinarian /or J«/y 

 1 840), yet has the fact of glanders having broken out on board of ship been 

 attested by Mr. Mogford (see Veterinarian /or Aug. 1840), as well as by 

 Smith, at page 213 of the prcbcnt volume.
